ERJ-S08F6651V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F6651V is a 6.65 kOhm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This part is rated for automotive applications under AEC-Q200 and features anti-sulfur construction. The part is currently active in production with 755 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified manufacturers is needed while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F6651V is determined by strict equivalence across the following critical parameters:

Resistance value: 6.65 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

All substitute parts listed below meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in feature sets (such as anti-sulfur or moisture-resistant coatings) do not affect functional substitutability for standard circuit applications.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the ERJ-S08F6651V and are suitable for direct replacement in circuit applications requiring 6.65 kOhm ±1% resistors in 1206 package format.

For new designs, select from parts with Active product status: AC1206FR-076K65L (YAGEO), CR1206-FX-6651ELF (Bourns Inc.), CRCW12066K65FKEA (Vishay Dale), RC1206FR-076K65L (YAGEO), or RMCF1206FT6K65 (Stackpole Electronics Inc.).

The ERJ-8ENF6651V carries a "Not For New Designs" status and should be used only for legacy system maintenance or when existing design documentation specifies this part number.

For automotive applications requiring AEC-Q200 certification, select from: ERJ-S08F6651V, ERJ-8ENF6651V, CRCW12066K65FKEA, or RMCF1206FT6K65.

All parts are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF6651V be used as a direct replacement for ERJ-S08F6651V?

A: Yes, electrically and mechanically. However, ERJ-8ENF6651V carries a "Not For New Designs" status. Use only for legacy system maintenance or when existing documentation specifies this part.

Q: Are all substitute parts suitable for automotive applications?

A: Not all. Only ERJ-S08F6651V, ERJ-8ENF6651V, CRCW12066K65FKEA, and RMCF1206FT6K65 carry AEC-Q200 automotive rating. AC1206FR-076K65L, CR1206-FX-6651ELF, and RC1206FR-076K65L do not list AEC-Q200 certification.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: These are additional protective coatings beyond the base thick film composition. Both are optional enhancements that do not affect core electrical performance or substitutability. The ERJ-S08F6651V includes anti-sulfur construction; some substitutes include moisture-resistant features instead. Both meet the same MSL 1 rating.

Q: Do physical dimension variations within the 1206 package affect substitutability?

A: No. All parts conform to the 1206 (3216 Metric) package standard. Minor variations in seated height (0.024" to 0.030") and length (0.122" to 0.126") are within package tolerance and do not affect circuit performance or PCB assembly compatibility.

Q: Which substitute part has the highest inventory availability?

A: ERJ-8ENF6651V with 48,811 units in stock, followed by RC1206FR-076K65L with 22,848 units and CR1206-FX-6651ELF with 25,445 units.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant with MSL rating 1 (Unlimited).
